Quality Control

Our (1S,2S)-1,2-Bis(2-Hydroxyphenyl)Ethylenediamine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high chemical purity and enantiomeric excess, meeting the stringent requirements for research and process chemistry. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants or an inert atmosphere.
